Discount Applications exposes line level discounts on the Order API
If you missed it at Unite this year, we've exposed line level discount information on the Order API with a new readable property: discount_applications. Take a look at the updated Order API reference for all of the details. This feature will enable more accurate accounting when discounts are involved in orders.
We look forward to seeing what features this enables, as always please leave questions and comments in the thread below.
